\usage{
  coskewnessSF(beta, stockM3, factorM3)
}
\arguments{
  \item{beta}{vector of length N or (N x 1) matrix of
  factor loadings (i.e. the betas) from a single factor
  statistical factor model}

  \item{stockM3}{vector of length N of the 3rd moment of
  the model residuals}

  \item{factorM3}{scalar of the 3rd moment of the factor
  realizations from a single factor statistical factor
  model}
}
\value{
  (N x N^2) coskewness matrix
}
\description{
  Estimate coskewness matrix using a single factor
  statistical factor model
}
\details{
  This function estimates an (N x N^2) coskewness matrix
  from a single factor statistical factor model with k=1
  factors, where N is the number of assets.
